Attitudes and information about smoking have changed.
Explanation:
Positive transformation of human attitude towards smoking due to increased knowledge and information regarding the ill effects of smoking have been a great social determinant of tobacco use.
The socioeconomic, educational, cultural, and political conditions that an individual lives in determine his/her attitude or behavior towards smoking.
When a region prohibits public smoking, families living in the region and their culture condemn smoking as a social evil, banning promotion of tobacco products, highlighting the warning signs or health hazards due to smoking, control and prevention awareness programs, etc has made the people to be more aware of the dangerous side effects of smoking.
This knowledge transforms the attitudes which make an individual refrain from smoking.
